Default 103

For 2011 Harley has peped up the 103 engine a bit. They run pretty nice right out of the box, BUT anyone have any data on aftermarket mufflers and hi flow air intakes and just what you get out of them for the money spent on these new versions of the 103?
Dyno results tell the story.

I don't know, but my 103 for 2010 didn't feel much different than a 96" till I did a FuelMoto package on it (PC V, air intake, Jackpot mufflers) . Now it runs like I would have expected.

Go to the Fuel Moto web site, they have dyno charts for the changes you asked about

I did not know they tweaked the engine any but they did go to a lower gear, 30 tooth primary pulley from the 32 tooth higher ratio. Makes em seem stronger. All is good however and the Fuel Moto people listed above do have some dyno run info for different mods.

That stainless and catless headpipe of thiers along with the tripple nickle cam will put a smile on your face, especially it you buy the PC-5 from them already loaded with the correct MAPS for the mods you choose.

I added some Rhinehart mufflers but that was mainly for sound. My 103 runs great and doesn't need anything. Even runs strong riding 2 up. Much better than the bike I traded in with the 96 in it.

I'd like to know the same thing. I want to keep the warranty intact, but in a couple of weeks, the new Road King Classic is scheduled to arrive. Will definitely be changing the exhaust and air cleaner. Don't want to pay for multiple remappings, so the cam might get switched out as well. Andrews? What do you guys think is the best one for this motor?

I've got the 103 in my 2011 Street Glide. With V&H Power Duals, Monster Ovals, PCV, High Flow Air and Woods 555 Cams, I am getting 99.4 hp, and just over 103 ft pounds of torque. Bike rides great and really pulls hard starting at 3,000.

I went from a 2004 carbed Fatboy with the "88" to a 2011 Road King Classic with the "103". I can tell a diffference and I can kick it in the *** without every LEO in the area being alerted by the noise.

There's some great cams for the 103. Some good ones to have a look at include the Cycle Rama 575, Woods 5 and Woods 555. Harley's stage II cams for the 103 are the SE255, good on the low end, but somewhat limited in overall performance.

There's no "best" cam. Best for you really depends on what your goals are for your bike.
